Abstract
Abstract An additive transfer device for storing and transferring of a medicament to a solution container such as an I.V. bag having an exposed port. The transfer device is accommodated in the neck of an additive container having a pierceable sealing element. A piercing guide member has a projecting tubular portion which extends into the tubular neck and affords a guide passageway for a piercing member with interlocking means being disposed in conjunction with the piercing guide member and the piercing member whereupon after their interlocking, the sealing element in the neck of the additive container is pierced. Wall means are provided from either the piercing guide member or the piercing member and fits over the tubular port of the I.V. bag. In the preferred embodiment, a needle guard member is utilized to actuate the interlocking means and afford the piercing of the pierceable sealing element. When the opposing pointed end of the piercing element is pierced through the I.V. port, communication can be made between the additive container and the I.V. bag.
